So damn good. I for one think the ending was perfect, though some of the arcs like splitting up felt clunky. If it continued it would be a different story, less angst, and the leads are no longer the same people introspecting on the same personal issues. A few more episodes would be fine, one for Metia maturing, one for Youthanasia rocking more grotesque, but it neither overstayed its welcome nor had too few.
Metia's slightly underwhelming origin and the partners dying off-page before their country exploded in population and made it big are ideal for a story about anticlimax!
Clunky storytelling is somehow part of the charm of this author and setting anyhow. That and the roughly equal fanservice
that suits it more than detracts from my suspension of disbelief. Hot immortals can dress however.
Even if you don't feel it now, you may look back on this as memorable if not the right end, as the most tonally consistent end, for the repeated anticlimax. Anything too grim, too positive, or too much political power wouldn't fit.
